One YG-4 trailer mounted hydroseeder has been smoothly delivered to a slope engineering client in Zimbabwe and put into on-site hydroseeding construction. Faced with the common working conditions of fill slopes and soil-rock mixed slopes across Zimbabwe, the client compared multiple hydroseeding equipment for sale and finally selected this hydroseeder trailer that allows direct soil feeding. Its unique mixing design of the hydroseeding tank helps the engineering team cut fiber consumption and reduce construction budgets, delivering a reliable solution for soil and water conservation and vegetation restoration of local road slopes.
This cooperating client is a local slope engineering contractor in Zimbabwe, undertaking road supporting greening and fill slope ecological restoration projects. The working conditions of this project are as follows:
Slope Type: Fill soil slope, pure soil slope, soil-rock mixed slope, which are very typical slope types for infrastructure projects in Zimbabwe;
Slope Parameters: Gradient within 45–50°, slope length of about more than 20 meters;
Construction Requirement: Hydroseeding thickness controlled within 3–4cm, and the sprayed layer needs good resistance to rain erosion;
Client’s Previous Pain Points:
The hydroseeder used before cannot add soil directly into the hydroseeding tank and relies on a large amount of fiber as the matrix, resulting in high material procurement costs;
Simple mixing structure causes severe slurry stratification. Grass seeds and fertilizers tend to sink to the bottom, leading to unstable germination rates and heavy workload for later maintenance;
Fixed hydroseeders are inconvenient to move. The project has scattered construction points, and relocation requires crane support, which is time-consuming and labor-intensive;
Local projects have strict budget control. The client hoped to reduce matrix costs and shorten the construction period while ensuring re-vegetation effects.
After comparing hydroseeding equipment from different brands and comprehensively evaluating adaptability, procurement cost, consumable cost, and transfer convenience, the client finally chose the YG-4 trailer mounted hydroseeder.
Solution Provided by YG
The delivered YG-4 trailer mounted hydroseeder is one of the few models supporting direct soil feeding operation. It can work with three-dimensional geonet and wire mesh for slope protection construction. Its core advantages are listed below:
Direct soil feeding for hydroseeding greatly reduces the consumption of fiber matrix, effectively cuts the overall construction cost, speeds up hydroseeding work, and improves grass seed germination rate and later survival rate;
Compact whole machine with trailer chassis design. It can be towed directly by vehicles without hoisting equipment, ideal for low slopes and scattered multi-point construction;
Dual Mixing System: Horizontal screw conveying mixing + reflux vertical flushing mixing. With dual mixing coordination, the slurry inside the hydroseeder tank is well mixed. Grass seeds, soil, fertilizers, and matrix are fully blended to guarantee uniform seedling emergence and stable growth;
Dual Hydroseeding System: Built-in universal direct spraying system + hose spraying system. Direct spraying is adopted on open slopes, while hose spraying can be used for long-distance areas, slope bottoms, and corners for more flexible coverage.
Important Notes
This series belongs to small hydraulic hydroseeding equipment, suitable for small and medium-sized projects with hydroseeding thickness around 2–3cm; this project is constructed within 3–4cm;
If the soil at the construction site has extremely high sand content or heavy viscosity, this model is not recommended. YG high-power hydroseeders (125KW, 130KW models) are suggested instead.
On-site Construction Performance & Project Results
After the YG-4 trailer mounted hydroseeder arrived at the Zimbabwe site and finished commissioning, it was quickly put into slope hydroseeding work. The on-site performance met the client’s expectations:
Easy Relocation: The hydroseeder trailer adapts to simple on-site roads in the local area. It can be towed by a tractor and transferred quickly between different construction slopes, saving time for hoisting, disassembly, and assembly;
Stable Mixing: The dual mixing structure of the hydroseeder tank works continuously. Soil, grass seeds, rice husk matrix, and water-retaining agent are evenly mixed, and the slurry is not prone to stratification and sedimentation;
Strong Adhesion: The slurry has strong adhesion after spraying onto soil and soil-rock mixed slopes. Combined with three-dimensional geonet laying, its anti-erosion capacity in rainy seasons is significantly improved;
Cost and Effect Up to Standard: The client reported that fiber consumable consumption dropped significantly and material expenditure was reduced. Seedlings emerge evenly, and the grass seed germination rate is much higher than that of the previously used equipment;
Perfect Working Condition Match: It fully satisfies the construction requirements of this project: gradient ≤50°, slope length of more than 20 meters, and hydroseeding thickness within 3–4cm.

Suitable for More Similar Projects in Southern Africa
This hydroseeder trailer is not only applicable to Zimbabwe, but also highly versatile for similar soil and water conservation and ecological restoration projects across Southern Africa. Applicable scenarios include:
Highway and embankment slope greening;
Reclamation of small mines and tailings slopes;
Riverbank and irrigation canal slope protection;
Ecological restoration of earth fill slopes.
Model Selection Reference
YG-2:2m³ tank, suitable for tiny and scattered small greening projects;
YG-4 (model selected by this client): 4m³ tank, 1000㎡ hydroseeding area per tank, the mainstream option for small and medium slope projects in Southern Africa;
YG-6: 6m³ tank with larger hydroseeding area per tank, suitable for projects with tight schedules and large daily hydroseeding volume.
Tip: For sites with a high proportion of sandy soil or heavy clay, YG high-power hydroseeder models are preferred.
Hydroseeding Slurry Ratio Guidance & On-site Operation Precautions
The slurry is mixed inside the tank. Recommended basic ratio: Water: Soil: Rice husk and other hydroseeding matrix = 1:0.5–1.5:0.5
Ratio Reference: The soil proportion in the formula is tested based on sandy soil; for clay construction, the soil adding ratio should be appropriately reduced to avoid thick slurry blocking pipelines;
Conveying Distance Reminder: Due to different specific gravity of slurry materials, the direct spraying range and hose conveying distance of hydroseeding will vary greatly;
Construction Limits: Hydroseeding thickness ≤3–4cm, gradient ≤45–50°, slope length controlled at about 20 meters;
Construction Suggestion: Lay three-dimensional geonet or wire mesh before hydroseeding, and spray slurry on the mesh to further enhance slope soil fixation and anti-erosion effect.
Q: Can the YG-4 hydroseeder trailer work with water-retaining agent and slow-release fertilizer for hydroseeding?
A: Yes. When preparing slurry, a water-retaining agent, slow-release fertilizer, grass seeds, soil, and matrix can be added into the tank together. The dual mixing system can achieve full mixing. It is very suitable for the arid and low-rainfall slope environment in Zimbabwe, improving water retention of seeds and long-term growth.
Q: Can the YG-4 exported to Zimbabwe perform hydroseeding with direct soil feeding?
A: Yes. The core advantage of YG-4 is supporting direct soil feeding construction to cut fiber procurement costs and improve seedling emergence results. It can work together with three-dimensional geonet and wire mesh.
Q: What are the main wearing parts of the equipment? How long is the spare part lead time?
A: Main wearing parts include spray nozzle, delivery hose, mixing liner, sealing parts, etc. A set of basic wearing parts can be supplied together with the machine. Spare parts are available for export shipment, and a separate quotation is acceptable to guarantee continuous construction at Southern Africa sites.
Q: How to clean the hydroseeder tank after hydroseeding work?
A: After each operation, add water into the tank for circulating mixing, then drain residual mud inside the tank and pipelines to prevent slurry from caking and blocking the mixing mechanism and spray pipes, extending the service life of the equipment.
Q: Can YG-4 be used for hydroseeding greening on high and steep mine slopes?
A: YG-4 is suitable for low slopes with a gradient within 45–50° and a slope length of more than 20 meters. It is not recommended for high and steep mine slopes with steeper gradients and longer slope length. YG high-power hydroseeding equipment is recommended instead.
